Phrynosoma solare, the regal horned lizard, is restricted to the Sonoran Desert in south-central Arizona east to extreme southwestern New Mexico, south through most of Sonora (including Isla Tiburon) and into northern Sinaloa, Mexico. P. solare can be distinguished from other horned lizard species by the following: one row of lateral abdominal fringe scales; four large occipital horns, in contact at base and continuous with six temporal horns forming a large crown of ten horns; nostrils inside the canthus rostralis; and ventral scales keeled.
